provements in Time-Printing Machines, of

which the following is a specification.

This invention relates to printing devices and mechanism for operating `the same at predetermined times, and is particularly designed for use with a cash-register or stock-.

ticker, although the invention may advantageously be employed in a number of other applications.

Our invention has, primarily, for its object to produce an eiiicient marking machine which will register upon a paper, tape or ribbon characters designa-ting the time in which portions of the paper are presented into printing positions.

With this and other ends in view, the invention consists in the novel construction and combination of parts, as will be-hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of an automatically operated printing device embodying our invention and with the containing case shown in section and the printing mechanism in operative position. Fig. 2 is a similar view with the printing mechanism in inoperative position.

In the drawings, the reference numeral 5 represents a casing inclosing the printing mechanism and a time-motor or clock 6 whereby such mechanism is operated. AV

movable frame comprised of arms 7 and 8 is ulcrumed by a pivotal pin 9 toa bracketsupport 10.

Journaled in the Jframe-arm 8 is a spindle 11 having mounted thereon a type-wheel 12 provided on its periphery with aseries 0f projections 121 carrying type-numerals designating successive periods of time, as 1 1:30, 2, 2:30, etc., to 12. To the face of said wheel is a ratchet wheel 13 provided with teeth, corresponding in number to the number of projections 121 provided on the type-wheel.

The frame arm 7 is provided at opposite sides of pin 9 with fingers 71 and 7 2 arranged to coact with the teeth 141 of a cam-wheel 14 which is mounted upon a spindle 15 and is movable in unison with a spur wheel 16 through the instrumentality of' a pinion 17. This pinion is mounted upon the arbor 18 `which Vcarries the minute hand of the clock and, in consequence, is rotated once in each hour, although it may be otherwise connected therewith as by an intermediate gearwheel, or by a tra-in of wheels, to get any otherrdesired speed of rotation. Said pinion is provided with two teeth 171 and 172 disposed diametrically opposite each other, hence the spur wheel is advanced thereby a tooth, so to speak, every half-hour, resulting in the cam-wheel 14 Vbeingl similarly moved to cause its teeth to successively encounter the finger 71 of the frame and force the lever arm 8 downwardly tov swing the type-wheel into printing position (see Fig. 1) and in opposition to a spring 19 which serves to restore the frame into its normal inoperative position, in whichl itis shown in Fig. 2, immediately after a tooth of the cam-wheel has passed thereby. The office of the other finger 7 2. is-to limit the extent of the successive movements of the cam-wheel.

20 represents al rod movable up and down in guide-lugs 81 provided on the Jframe and is formed at its lower end to serve as a pawl with respect to the ratchet wheel 13; to which end, the relatively weak spring 21 is interposed between the upper of said guide lugs and a head 2()1 provided on the rod and tending to thrust the rod upwardly until arrested by a iXed collar 202 on the rod engagratchet wheel and to the type-wheel which is operable therewith, to progressively move the type characters into printing positions.

23 represents a resilient blade which is secured to the frame arm 8 and frictionally presses against the face of the type wheel to overcome any momentum thereto subsequent to the action of the pawl.

As illustrated, the casing is formed with a base element 51 and in the ends of the casing are openings 52 and 53 for the passage of a paper tape, indicated by 211, upon which time records are to be printed.

Immediately below the type wheel is an elastic-body or cushion 25 which serves asa platen.

26 is an inlring ribbon which is unwoiind from and wound upon spools 27 and 28, respectively positioned in spaced relations at opposite sides of the type wheel. The spools are mounted upon spindles 271 and 281 journaled in suitable bearings provided, preferably, in the casing walls. rlfhe spool 28 is connected to its spindle to rotate therewith and provided on the latter is a ratchet wheel 29 which is given anL intermittent rotary movement through the agency of pawl 30 carried by the frame-arm 7 as shown.

The operation of the invention is as follows: As the pinion 17 is rotated by the clock arbor 18, the pinion teeth 17l and 172 are revolved to successively impart intermittent motion to the spur wheel 16 and likewise to the cam-wheel 111. When a camtooth is thus revolved, it actiiates the frame which carries the type wheel to swing the same down against the ink ribbon and the latter, in turn, against the article which isV to be printed, to accordingly thereupon print the type characters as presented. When this is accomplished, the spring 19 asserts its power to suddenly withdraw the type-wheel from the work and thus retain it untilagain affected by the following tooth of the cam-wheel. The type-wheel is progressively advanced as before explained, so as to have the type characters record the progress of time.

1. In a time printing machine, a frame, a rotatable type-wheel carried by said frame, a spring connected to said frame, clock-actuated devices acting in opposition to said spring for causing the frame to carry said typewheel into printing position, and means influenced by the successive movements of the frame to eii'ect intermittent rotary movements to the type-wheel.

2. In a time printing machine, the combination with clock-work and a type-wheel, of a spring for yieldiiigly maintaining the type-wheel in inoperative position, a cam Wheel, a spur-gear operable in unison With said cam-wheel, and a. pinion operated by said clock-work and adapted to actuate the cam-wheel so as to cooperate with said spring to afford intermittent reciprocatory movements to the type-wheel.

'3. In a time printing` machine, a frame, a rotary type-wheel carried by the frame, a

cani for actuating said lever to move said l type-wheel into printing position, clockwork for operating the cam, a spring acting to retract the type-wheel from such printing position, and devices for rotatably moving the type-wheel when thus retracted.

4. In a time printing machine, the combination with clock-work and a type-wheel, of a spring for yieldingly maintaining the type-wheel in inoperative position, a camwheel, a spur-gear operable in unison with said cam-wheel, a pinion operated by said clock-work and adapted to actiiate the camwheel so as to coperate with said spring to afford intermittent reciprocatory movements to the type-wheel, and ratchet and pawl devices inade operative by said spring for imparting intermittent rotary motion to said type-wheel.

5.

7. In a time printing machine, the combination of a vibratile frame provided with a finger, a spindle carried by the frame, a type-wheel and a ratchet-wheel mounted on said spindle, aspring connected to said frame and serving to yieldingly hold the same to retain the type-wheel in inoperative position, a cam-wheel provided with teeth which are severally adapted to be engaged with said finger to swing the frame into 'printing position with respect to the typewheel, gear-wheels for operating t-he cam, clock-work for actuating said gear-wheels, and a pawl engaging with said ratchet wheel to impart rotary movement thereto in each movement of the same into inoperative position.

8. In a time printing machine, a vibratory frame, a type-Wheel carried by said frame, a toothed cam, clock-actuated means for imparting intermittent rotary movements to said cam whereby the teeth thereof Will successively swing the frame into printing position with respect to the type- Wheel, means acting in opposition to the cam-teeth for swinging the frame in a contrary direction, and means effected by the swinging of the frame for imparting intermittent rotary movements to the type- Wheel.
